Short‐Term Reproducibility Over Time of Right Ventricular Pulse Pressure as a Potential Hemodynamic Sensor for Ventricular Tachyarrhythmias
Key result
The decrease in right ventricular pulse pressure was highly reproducible across two separate episodes of ventricular tachycardia (-13 ± 2 mmHg vs -12 ± 2 mmHg; P=NS).
Why the study?
Is the measurement of right ventricular pulse pressure reproducible during separate episodes of ventricular tachyarrhythmias?

Right ventricular pulse pressure demonstrates short-term reproducibility during ventricular tachyarrhythmias, supporting its potential utility as a hemodynamic sensor in implantable cardioverter defibrillators.
Cite This Study
Ellenbogen et al. (1992) conducted an observational in Ventricular Tachyarrhythmias (n=10). Right ventricular pulse pressure measurement vs. Episode 1 vs Episode 2 was evaluated on Decrease in right ventricular pulse pressure (p=NS). The decrease in right ventricular pulse pressure was highly reproducible across two separate episodes of ventricular tachycardia (-13 ± 2 mmHg vs -12 ± 2 mmHg; P=NS).
